The set-up is this. Bogart (as Philip Marlowe) has been captured by the bad guys and is being held in a remote cottage in handcuffs. This is his escape. Returning, the bad guys drive up and, as ordered, Lauren Bacall screams inside the cottage to distract them. The rest is clear enough.
Max Steiner, a Viennese composer who studied with Brahms and Mahler, wrote the music. Again, as we saw with “The Sting,” there is little dialogue, the music carries the scene. Steiner composed a Straussian tone poem as score to this movie, with themes reminiscent of Till Eulenspiegel and the Symphonia Domestica. Marlowe’s theme is heard for the first time in this scene (not the movie) just as he closes the door to the car — it’s a trickster’s theme, perfectly suited to Marlowe. Steiner then repeats the theme in several guises shortly thereafter, and uses fragments of it as well.
The high point is Canino’s (the bad guy’s) death, when the Warner Bros. orchestra is unleashed.
